Can someone tell me how long errors are held in the event database? We are using APM 10.1. A user was looking at a graph of Errors Per Interval for a Tomcat JVM and saw some errors on the graph. When they clock on the Errors tab they do not see anything. This is for a time period occurring about 8 days ago. When I go look into any other JVM, I do not see any errors for this time period either.
